We look at the division of 65976899 by 41 
The aim is to understand the frequency of 41 in 65976899.

Going ahead to step 1:
When dividing 6 by 41, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 41

Advancing to step 2:
41 can be fit into 65 1 times, resulting in a remainder of 24.
The next digit of our result is 1. 
Result so far: 1.0
If we take 41 away from 65, we end up with 24.
Append the next digit (9) from the dividend to 24 and continue with: 249 / 41

Moving on to step 3:
The number 41 fits into 249 6 times, leaving a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 246 from 249 and we're left with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 41

On to step 4:
37 divided by 41 is 0 with a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 160.0
Deduct 0 from 37 and we're left with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 41

Let's proceed to step 5:
376 divided by 41 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 1609.0
Deduct 369 from 376 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 41

Going ahead to step 6:
41 goes into 78 1 times with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 16091.0
Subtract 41 from 78 to get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 41

Advancing to step 7:
The number 41 fits into 379 9 times, leaving a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 160919.0
If we subtract 369 from 379, we get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 41

Step 8:
If we divide 109 by 41, we get 2 and a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 1609192.0
Subtracting 82 from 109 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
If we divide 270 by 41, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 1609192.6
If we subtract 246 from 270, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
The number 41 fits into 240 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1609192.65
If we subtract 205 from 240, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
41 can be fit into 350 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 1609192.658
Deduct 328 from 350 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
When dividing 220 by 41, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 1609192.6585
The remainder is 15 after subtracting 205 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
41 can be fit into 150 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 1609192.65853
Subtracting 123 from 150 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 14:
If we divide 270 by 41, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 1609192.658536
The remainder is 24 after subtracting 246 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 15:
41 goes into 240 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1609192.6585365
Deduct 205 from 240 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 16:
350 divided by 41 is 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 1609192.65853658
If we take 328 away from 350, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 1609192.65853658 with a remaining 2.2e-08.
